In the near term, the manufacturer will use 49 acres acquired from Pulaski County to extend its 1.1- mile Customer Experience Track. The remaining land will serve future business expansion. SOLIDIA SECURES BONDING ELEMENT, METHOD PATENT The U.S. Patent and Trademark Office has recognized the unique structure of Solidia Technologies' eponymous concrete, designed and produced with conventional aggregates and processes, but bearing an alterna- tive to hydraulic binders that reacts with carbon dioxide versus water. U.S. Patent No. 9,868,667, "Bonding Element, Bonding Matrix and Composite Material Having the Bonding Element and Method of Manufac- turing Thereof," covers the composition of matter of the distinctive, non-hydraulic, CO 2 - cured concrete available as Solidia Concrete. "The hydrate bonds in conventional con- crete can compromise that material's strength and durability," explains Solidia Chief Tech- nology Officer Nicholas DeCristofaro, Ph.D. "With CO 2 -cured concrete, bonding elements based on silica and calcium carbonate create a wide range of attractive properties, includ- ing mechanical strength, [and] resistance to freeze-thaw deterioration [or] sulfate attack." A Rutgers University-patented process to which Piscataway, N.J.-based Solidia Tech- nologies has exclusive rights, starts with an energy-saving, sustainable cement, specifica- tion of which equates to a carbon footprint reduction up to 70 percent when measured against conventional portland cement con- crete. Using the same raw materials and existing plant equipment, CO 2 -cured Solidia products and structures are higher perform- ing, cost less to fabricate, and cure in less than 24 hours, company engineers contend. Currently in commercialization for large- and small-scale applications, the initial technology focus at Solidia's northern New Jersey headquarters was unreinforced pre- cast and unit masonry. Engineers are now developing commercial processes for rein- forced products, including aerated concrete, railroad ties, architectural panels and hollow core plank. Paving stones are among early applica- tions in the Solidia Concrete commer- cialization phase. Volvo Trucks expands customer experience
